Its capacity is rather impressive, 3100 mAh, and should provide juice to the iPhone for 750 hours in standby or up to 21 hours of video playback. It also includes a flash light for emergency use as well as for low light photos. It can in addition be used to charge all USB port devices. Nevertheless, such a good looking product has a drawback, its price: 99.95 USD (and 99 Euro in EU, 35% more expensive…).
